J.J. McCarthy vs Patrick Mahomes: Who Should You Start?
The numbers tell a clear story here. Patrick Mahomes put up 20.4 fantasy points per game for the Kansas City Chiefs in 2025, while J.J. McCarthy managed 12.5 across 10 games with the Minnesota Vikings. A 7.9-point weekly edge is substantial at the quarterback position.
That 7.9-point weekly advantage for Patrick Mahomes is meaningful but not automatic. Fantasy football is a week-to-week sport, and the answer to "who should I start" often changes based on opponent, recent form, and game environment. Season averages set the baseline; weekly context makes the call.
Patrick Mahomes offers meaningful rushing upside with 422 yards on the ground in 2025, which separates his floor from a pocket passer like J.J. McCarthy (1632 passing yards, 11 touchdowns). In games where the passing matchup looks ugly, that rushing production can be the entire difference on a start/sit call.
Bye weeks matter for roster construction: J.J. McCarthy sits Week 6 while Patrick Mahomes is off Week 10. If you are deciding between the two as a season-long roster hold, the staggered byes actually work in your favor.
